TECHNICAL FIELD

The subject disclosure relates to wireless communications and, more particularly, to a scalable policy management and deployment architecture in a wireless communications network.

BACKGROUND

With the increasingly high demand for mobile broadband services, network operators are rushing to deploy large-scale networks. Such networks include Long Term Evolution (LTE) networks as well as other types of networks. The new services that will be supported on the networks are both data (particularly video) and voice. These services require Quality of Services (QoS) and some services (such as voice) will require guaranteed bit rate bearers to deliver good customer experience. In addition, operators need to differentiate, control, and bill different types of traffic on the network.

Traditionally, policy management for telecommunication networks has focused mainly on network management. In recent years, however, as wireless networks have migrated toward Internet Protocol (IP)-based service environments, policy management has been gaining increasing importance to telecommunication networks that manage and control those services. Thus, policy management becomes an important component in the deployment.

Although policy management has been standardized in some networks, such as LTE networks, the deployment use cases and architecture are not covered in the standard and it is up to each operator to decide how to deploy the network based on its services and use cases. Further, each separate service, or class of services, requests the networks to apply different policy mechanisms, depending on the type of request being handled. Additionally, most of the management functions are scattered across the network and tend to be performed in a localized and static fashion.

For instance, when a user of a networked portable device, such as a cell phone, Personal Digital Assistant (PDA), laptop, or the like, request(s) access to one or more services offered through the one more networks, there is no common manner to track access and user requests based on type of services, such as voice. Further, there is no common means to manage, store, update, and so forth, the policies.

In a large scale LTE deployment, to support voice and other services, it is important to track media sessions and provide end-to-end session tracking and management. Further, there is no common architecture that enables scaling of policy framework deployment in such networks.

The above-described deficiencies of today's policy deployment architectures are merely intended to provide an overview of some of the problems of conventional systems, and are not intended to be exhaustive. Other problems with conventional systems and corresponding benefits of the various non-limiting embodiments described herein may become further apparent upon review of the following description.

DETAILED DESCRIPTION Overview

Network deployment should support IP-based and non-IP based service traffic, including voice services and mobile data services. For example, there are challenges in deploying voice over Long Term Evolution (LTE) networks (as well as other networks) since such deployment can comprise Internet Protocol (IP) Multimedia Subsystem (IMS) systems in order to manage voice media. For some applications, the voice media stream should be Quality of Service (QoS) enabled and have a guaranteed bit rate. In addition, the media should be anchored outside of the LTE/EPC (Evolved Packet Core) network, such as with a session border controller (SBC). Thus, it would be desirable to provide network elements that can keep track of these media sessions and that can provide end to end session tracking and management.

In addition, the current policy framework deployment can be difficult to scale up in order to support projected user and traffic growth in the future. Additionally, there currently is no mechanism to manage the complexity of networks in terms of policy related services and information. Further, the current deployment is very difficult to scale up in terms of additional Policy and Charging Rules Function (PCRF) deployment.

Thus, it would be beneficial to provide a scalable and deployable solution that will address these problems. Further, it would be beneficial to provide a scalable and deployable solution that will support a communication network with the projected (as well as more than projected) user and traffic growth.

Herein, an overview of some of the embodiments for a scalable policy deployment architecture has been presented above. As a roadmap for what follows next, various exemplary, non-limiting embodiments and features for policy deployment architectures are described in more detail. Then, some non-limiting implementations and examples are given for additional illustration, followed by representative networks and environments in which such embodiments and/or features can be implemented.

A Scalable Policy Deployment Architecture in a Communication Network

By way of further description with respect to one or more non-limiting ways to provide a scalable policy deployment architecture, a high-level block diagram of an exemplary communication system is illustrated generally by FIG. 1. The communication system can be included in an environment, which can be a communications network and/or a set of communication networks. Network types can include Universal Mobile Telecommunications Systems (UMTS), Long Term Evolution (LTE), High Speed Packet Access (HSPA), Code Division Multiple Access (CDMA), Multi-Carrier Code Division Multiple Access (MC-CDMA), Single-Carrier Code Division Multiple Access (SC-CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Single-Carrier FDMA (SC-FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), and so on. Although the various aspects and examples are discussed herein with respect to a LTE network, it should be appreciated that the disclosed aspects can be utilized with other networks and any references to LTE networks are for purposes of simplicity of describing the various aspects.

The environment can include a multitude of network entities 100, wherein each entity (or a set of entities) can perform a function that is different from a function performed by another entity (or another set of entities). Network entities, can include, but are not limited to, Diameter Routing Agents (DRAs), Balance Manager (BMs), Policy and Charging Enforcement Functions (PCEFs), Policy Controlling and Rules Functions (PCRF), Session Border Controllers (SBCs), gateways (e.g., messaging gateway), application and content providers, and so forth.

Further, the network entities 100 can deploy one or more policies. As used herein, “policies” refers to a set of one or more rules that a network operator can define and enforce in a telecommunications network (e.g., environment). The policies can be exchanged and can be applied both within an operator domain and across different operator domains. The policies are input in the form of one or more arriving policies 102 to a consolidation component 104. The consolidation component 104 is configured to manage the one or more arriving policies, wherein each of the arriving policies can be associated with a different network entity. Further, the consolidation component 104 is configured to consolidate the one or more arriving policies 102. At least a subset of the consolidated policy information 106 is conveyed to a deployment component 108 that is configured to implement the network related policies on a multitude of service zones included in the environment.

As shown, consolidation component 104 and deployment component 108 can be included in a communications apparatus 110 or network entity. In accordance with some aspects, the communications apparatus 110 (sometimes referred to herein as a Policy Access Gateway (PAG)) can be configured to perform various functions usually performed by a DRA. In accordance with some aspects, the communications apparatus 110 is configured to perform functions for processing policies. According to some aspects, the communications apparatus 110 is configured to perform both DRA functions as well as additional functions for policy processing. Further, the communications apparatus 110 can be configured to retain state and session information. Additionally, the communications apparatus 110 is configured to provide intelligent policy routing between PCEFs and their managing PCRF instance. Further, according to some aspects, the communications apparatus 110 is configured to provide policy and charging control for PCEFs that are located in a large number of service zones, wherein the service zones can be in the same or in different National Data Centers (NDC).

In an embodiment, the communication system illustrated by FIG. 1 can differ in operation from a conventional communication system in order to provide additional benefits over those achievable by systems that employ a non-scalable policy deployment architecture. For instance, the communication systems disclosed herein are scalable and can be deployed in a very large network that support hundreds of millions of users.

Illustrating other aspects, FIG. 2 is a block diagram showing a consolidation component 202, according to an aspect. The consolidation component 202 is configured to receive, manage, and consolidate network related policies. As discussed with reference to FIG. 1, the consolidation component 202 can be included in a communication apparatus or PAG.

The consolidation component 202 comprises a receiver component 204 that is configured to obtain network policy information 206 from a multitude of network entities 208, labeled as network entity_(i) through network entity_(N), where N is an integer. Each of the network entities 208 can perform a different function, or subsets of the network entities can perform different functions, wherein a subset, as used herein comprises one or more network entities. For example, a first subset of network entities can perform a first function, a second subset of network entities can perform a second function, a third subset of network entities can perform a third function, and so on.

For example, a network entity can be an Application Function (AF), which is an element offering applications that need dynamic policy and/or charging and control over an IP-Connectivity Access Network (IP-CAN) user plane behavior. The AF can receive an indication that the service information is not accepted by a PCRF together with service information that the PCRF would accept. In that case, the AF rejects the service establishment to the user equipment (or user device). If possible, the AF can forward to the user equipment an indication of the service information that the PCRF would accept. AF may communicate with multiple PCRFs and contact the appropriate PCRF based on either an end user IP Address and/or a user equipment identity of which the AF is made aware.

In a further example, another network entity is a Subscription Profile Repository (SRP) logical entity that includes all subscriber/subscription related information needed for subscription-based policies and IP-CAN (Internet Protocol Connectivity Access Network) bearer level charging rules by the PCRF. The SPR may be combined with or distributed across other databases in the operator's network. SPR may provide information including, but not limited to, Subscriber's allowed services, Information on subscriber's allowed QoS, Subscriber's charging related information, and Subscriber category.

Another example of a network entity and its related functionality is a PCEF, which examines packets passing though a gateway and enforces control and charging policy decisions on the packets. These policy decisions are generated by a policy decision engine, which can be called a Policy Control and Charging Rules Function (PCRF) in 3GPP. A Gx reference point carries subscriber information and access sessions information from the PCEF to the PCRF and policy decisions from the PCRF to the PCEF.

The consolidation component 202 also comprises a routing component 210 that is configured to provide routing between the network entities 208 and a multitude of service zones 212, labeled as service zone₁ though service zone_(M), where M is an integer. In an example, the routing between the network entities 208 and the multitude of service zones 212 might have previously been performed by a Diameter Routing Agent (DRA), according to conventional deployment architectures. However, in accordance with the disclosed aspects, the routing is performed by the routing component 210 or another component of the communications apparatus (or PAG). In accordance with some aspects, service zones 212 comprise five or more service zones, wherein the routing component 210 further provides routing between the network entities 208 and the five or more service zones 212.

Illustrating other aspects, FIG. 3 is a block diagram showing a deployment component 302, according to an aspect. The deployment component 302 is configured to implement the network related policies on a plurality of service zones. As discussed with reference to FIG. 1, the deployment component 302 can be included in a communication apparatus or PAG.

The deployment component 302 can comprise a management component 304 that is configured to manage the multitude of service zones 212 (labeled as service zone₁ though service zone_(M), where M is an integer) based on the network policy information 206 (received by a consolidation component 306 and conveyed to deployment component 302).

In an aspect, the managing by management component 304 is performed on behalf of the different network entities 208. Thus, deployment component 302 can comprise a mapping component 308 that is configured to track the network policies (or consolidated network policies) and associate each policy or set of policies to each service zone. In accordance with some aspects, the mapping is performed at a device level, wherein each policy (or set of policies) is matched to a user equipment level. In accordance with some aspects, the mapping component 308 tracks user service activities and network nodes that support the user service activities. For example, the mapping component 308 can track a first activity for a first user service and a second activity for a second user service.

For example, mapping component 308 can be configured to track the user service activities based on the IP flows that carry the bits for these services. The requests can be received from user agents, which are applications on the user device or user equipment, for example. The user service activities can include, but are not limited to, a voice call, an instant message, an Internet browsing session, and so forth.

To further describe the various aspects provided herein, FIG. 4 illustrates a conventional network deployment architecture 400 that does not incorporate the disclosed aspects. This architecture 400 can produce PCRF scaling problems. Included in the architecture 400 is a common service zone 402 that comprises one PCRF instance 404 in a national data center. The PCRF instance 404 is configured to support up to four traffic service zones, labeled as First Zone 406 (Zone 1), Second Zone 408 (Zone 2), Third Zone 410 (Zone 3), and Fourth Zone 412 (Zone 4). Thus, there is a one to four (1:4) relationship between the PCRF instance 404 and its service zones.

Each Zone comprises a PGW 414-420, which comprises a PCEF 422-428, and a Serving Gateway (SGW) 430-436. A policy session bind correlation and load balancing between the PCRF 404 and PCEF 416 are achieved though a predefined static configurations on each side. To support additional traffic service zones, additional PCRFs need to be added since the PCRF cannot support more than four service zones (per the 1:4 ratios). This scaling mechanism can present operational challenges as additional data centers are created within the communication network.

To overcome the scaling problem, FIG. 5 illustrates a scalable deployment architecture 500, according to an aspect. As illustrated, a PAG 502 (e.g., communication apparatus 110 of FIG. 1) is included in the deployment architecture 500. In accordance with some aspects, the PAG 502 can be based on RFC 3588 and relevant 3GPP standards for policy and charging control, which are incorporated herein by reference. Alternatively, the disclosed aspects do not depend on the 3GPP standard and other embodiments of the disclosed architecture apply to principles of the disclosed aspects in an architecture not fully compliant with 3GPP.

As illustrated, the PAG 502 can reside in a common service zone 504 and can interface with a PCRF 506. The PAG 502 can also interface with a plurality of service zones, labeled as a first zone 508 (Zone 1), a second zone 510 (Zone 2), and other zones up to zone p-1 512 and zone p 412, where p is an integer. Each zone comprises respective PGWs 516-522, PCEFs 524-530, and SGWs 532-538.

In accordance with some aspects, the PAG 502 performs functions similar to those of a Diameter Routing Relay and Proxy Agent for PCRF, as well as additional functions discussed herein. Thus, the PAG 502 can provide intelligent policy routing between PCEFs 524-530 and their managing PCRF 506 instance. Further, the PAG 502 allows P number of PCEFs to connect to their managing PCRF instance, which can provide large scale deployment flexibility. For example, zones can be added without the need to add additional PCRFs.

FIG. 6 illustrates an exemplary deployment architecture 600, according to an aspect. Included in the deployment architecture 600 is a Policy Access Gateway (PAG) 602 (e.g., communications apparatus 110 of FIG. 1). The PAG 602 is configured to interface with a multitude of network entities. For example, the PAG 602 can interface with a Balance manager 604 (BM) and Provisioning Systems 606. The BM 604 can manage, for example, quota gigabytes per month, which can track the amount of usage for each user equipment. Such usage can be tracked for billing purposes (e.g., pay per view) or for other purposes (e.g., statistical information, usage information, and so forth). The PAG 602 can also interface with a SPR 608, a PCEF 610, and PCRF 612, wherein there can be a multitude of PCRFs included in the architecture 600.

Further, the PAG 602 can interface with a Managed Services Provider (MSP) 614 over a Gx interface. The PAG 602 can also interface with Application and Content Providers 616 over an Rx interface, for example. Additionally, the PAG can interface with one or more DRAs 620, 622 and a Session Boarder Controller (SBC 618), which controls the signaling and the media streams involved in setting up, conducting, and tearing down voice calls or other interactive media and can comprise an Application Function (AP).

The PAG 602 is configured to consolidate all policy related functions. The PAG 602 is also configured to manage the network related policies. Further, the PAG 602 can comprise the standard Diameter Routing Agent (DRA) functions as defined by 3GPP. In addition, the PAG 602 can also be configured to perform other functions, such as processing policies and retaining some state and session information.

The illustrated deployment architecture 600 can be based on an existing network topology and can further provide support for future LTE network deployment. Thus, the disclosed aspects can support IP Multimedia Subsystem (IMS)-based services such as Voice (links to the Session Border Controller (SBC) for both signaling and media) and messaging (IP-SM-GW). Further, by deploying the PAG 602, as disclosed herein, the various aspects can provide scalability to the policy functions in large LTE deployments, which will be able to support hundreds of millions of users. The DRA 620 can take the diameter function and route the function and perform other standard routing functions.

FIG. 7 illustrates an exemplary communications apparatus, which can be a Policy Access Gateway (PAG) 700, according to an aspect. The PAG 700 can comprise a consolidation component 702 that is configured to manage and consolidate network related policies. The network related policies can be received from different network entities, wherein at least one network entity performs a first function that is different from a second function performed by a second entity. Also included in the PAG 700 is a deployment component 704 that is configured to implement the network related policies on a multitude of service zones (e.g., five or more service zones).

In accordance with some aspects, the PAG 700 is associated with a storage media 706. Although shown as external to the PAG 700, according to some aspects, storage media 706 can be contained, at least partially, within the PAG 700. Storage media 706 can be configured to retain at least one state and at least one session information related to a service in at least one service zone of the multitude of service zones.

An interface component 708 can be included in the PAG 700, in accordance with some aspects. The interface component 708 can be configured to communicate with the multitude of service zones on behalf of an entity (or two or more entities). Additionally or alternatively, the interface component 708 can be configured to communicate with the entity (or the two or more entities) on behalf of the multitude of service zones.

FIG. 8 illustrates a deployment architecture 800 that comprises multiple geographical locations, according to an aspect. The deployment architecture 800 can comprise two or more National Data Centers (NDC), illustrated as NDC A 802 and NDC B 804. Each NDC comprises a common service zone 806, 808. However, only common service zone 806 comprises a PCRF 810. The PCRF 810 communicates with PAG 812 and PAG 814. Each PAG 812, 814 supports a multitude of Zones, Labeled Zone 1, Zone 2, through Zone p-1, and Zone p.

Thus, the disclosed aspects can provide PCRF scaling for PCEF, where PCRF is not located in the same NDC with the PCEFs. The PCRF can provide policy and charging control for PCEFs from P number of traffic service zones in different NDC PAG-networks, which is a globally routable, secured, and dedicate network for PAG signaling for routing policy traffic.

By way of example and not limitation, policy based routing supporting PCRF scaling and policy geographic distribution (flexible deployment architecture (FIGS. 5 and 8) can be configured to provide support for standard policy routing functions.

In another example, the disclosed aspects can provide dynamic policy based transaction state tracking and management. This can provide a policy based tracking mechanism in addition to simple standard routing. With this mechanism, the network can keep track of the sessions between any network nodes for all subscribers and for each user's current services and the network elements that provide the services. With this intelligence, dynamic and customized services becomes possible.

FIG. 9 illustrates a flow chart for providing a scalable policy deployment architecture, in accordance with an aspect. At 902, routing between network entities and a plurality of service zones is provided. In accordance with some aspects, the routing between the network entities and five or more service zones is provided. Each of the network entities can support a different function. In accordance with some aspects, subsets of the network entities support different functions.

At 904, network policy information is received from the network entities. User service activities are tracked, at 906. The tracking of user service activities can comprise tracking a first activity for a first user service session and a second activity for a second user service session. In accordance with some aspects, the tracking comprises tracking a plurality of services provided to one user device. In another aspect, the tracking comprising tracking different network elements (or network entities) that facilitate the services. Further, different combinations of different network nodes that support the user service activities can be tracked.

The plurality of service zones are managed, at 908. The management of the plurality of service zones can be based on the network policy information. In accordance with some aspects, the management is performed on behalf of one or more of the network entities.

In accordance with some aspects, the method 900 can also include retaining at least one state and session information related to one or more services of one or more service zones of the plurality of service zones.

In one embodiment, a computer-readable storage medium comprises computer-executable code instructions stored therein, wherein in response to execution by at least one processor, the computer-executable code performs operations comprising tracking user service activities with respect to a wireless communication network and correlating the user service activities to different combinations of network nodes that support the user service activities. The user service activities can comprise a first activity for a first user equipment and a second activity for a second user equipment. In accordance with some aspects, the user service activities comprise a plurality of services provided to one user equipment. According to some aspects, the user service activities comprise different network elements that provide the services. The operations can also comprise providing routing between network entities and a plurality of service zones, receiving network policy information from the network entities with different functions, and managing the plurality of service zones based on the network policy information, wherein the managing is performed on behalf of the network entity.

By way of further description with respect to one or more non-limiting ways to provide scalable policy deployment, FIG. 10 is a schematic example wireless environment 1000 that can operate in accordance with aspects described herein. In particular, example wireless environment 1000 illustrates a set of wireless network macro cells. Three coverage macro cells 1002, 1004, and 1006 comprise the illustrative wireless environment; however, it should be appreciated that wireless cellular network deployments can encompass any number of macro cells, for example, 1004-1005 coverage macro cells. Coverage macro cells 1002, 1004, and 1006 are illustrated as hexagons; however, coverage cells can adopt other geometries generally dictated by a deployment configuration or floor plan, geographic areas to be covered, and so on. Each macro cell 1002, 1004, and 1006 is sectorized in a 2π/3 configuration in which each macro cell includes three sectors, demarcated with dashed lines in FIG. 10. It should be appreciated that other sectorizations are possible, and aspects or features of the disclosed subject matter can be exploited regardless of type of sectorization. Macro cells 1002, 1004, and 1006 are served respectively through base stations or eNodeBs 1008, 1010, and 1012. Any two eNodeBs can be considered a eNodeB site pair (NBSP). It is noted that radio component(s) are functionally coupled through links such as cables (e.g., RF and microwave coaxial lines), ports, switches, connectors, and the like, to a set of one or more antennas that transmit and receive wireless signals (not illustrated). It is noted that a radio network controller (not shown), which can be a part of mobile network platform(s) 1014, and set of base stations (e.g., eNode B 1008, 1010, and 1012) that serve a set of macro cells; electronic circuitry or components associated with the base stations in the set of base stations; a set of respective wireless links (e.g., links 1016, 1018, and 1020) operated in accordance to a radio technology through the base stations, form a macro radio access network (RAN). It is further noted, that based on network features, the radio controller can be distributed among the set of base stations or associated radio equipment. In an aspect, for UMTS-based networks, wireless links 1016, 1018, and 1020 embody a Uu interface (UMTS Air Interface).

Mobile network platform(s) 1014 facilitates circuit switched (CS)-based (e.g., voice and data) and packet-switched (PS) (e.g., internet protocol (IP), frame relay, or asynchronous transfer mode (ATM)) traffic and signaling generation, as well as delivery and reception for networked telecommunication, in accordance with various radio technologies for disparate markets. Telecommunication is based at least in part on standardized protocols for communication determined by a radio technology utilized for communication.
